Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 17636-1 was prepared by the European Committee for Standardization (CEN) in collaboration with ISO
Technical Committee TC 44, Welding and allied processes, Subcommittee SC 5, Testing and inspection of
welds in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).
This first edition, together with ISO 17636-2, cancels and replaces ISO 17636:2003, of which it constitutes a
technical revision.
ISO 17636 consists of the following parts, under the general title Non-destructive testing of welds —
Radiographic testing:
 Part 1: X- and gamma-ray techniques with film
 Part 2: X- and gamma-ray techniques with digital detectors
The main changes are that:
 the normative references have been updated;
 the document has been divided into two parts — this part of ISO 17636 applies to radiographic testing
with films;
 X-ray devices up to 1 000 kV have been included;
 the text has been editorially revised.
Requests for official interpretations of any aspect of this part of ISO 17636 should be directed to the
Secretariat of ISO/TC 44/SC 5 via your national standards body. A complete listing of these bodies can be
found at www.iso.org.

Introduction
This International Standard specifies fundamental techniques of radiography with the object of enabling
satisfactory and repeatable results to be obtained economically. The techniques are based on generally
recognized practice and fundamental theory of the subject, inspection of fusion welded joints with industrial
radiographic films.
